I am trying to convert the principles in "Isometric Game Programming with DirectX 7.0" to DBpro.
Just in case there is anyone interested... figured I would post some code examples as I go. I'll update as I go along, but not making too many promises as I never seem to finish things.
Anyways, Just place my horrible-NON-seamless ground tile (which actually helps in illustrating this example
) in a project folder with the following even More-Horrible code. Then press the [Space Bar] to flip between Diamond and Staggered map plotting. It also overlays the x,y Map-coordinates so you can see the different directions of the X and Y planes.
EDIT:changed to .png file as photobucket seems to autuomatically convert .bmp to .jpg
